Abstract: A power actuator for moving a closure panel of a motor vehicle between closed and open positions is provided. The power actuator includes an electric motor and a pinion gear supported for rotation in response to rotation of a motor drive shaft of the electric motor. An extensible rack having a plurality of rack teeth is configured for meshed engagement with pinion teeth of the pinion gear. The extensible rack is configured to move between a retracted position, corresponding to the closed position of the closure panel, and an extended position, corresponding to the open position of the closure panel, in response to rotation of the pinion gear. The rack teeth have circumferentially extending, arcuate outer peaks, as viewed along a longitudinal axis of the extensible rack to allow relative pivotal movement between the rack teeth and the pinion teeth, thereby inhibiting jamming between the extensible rack the pinion gear.
